Ford F-150 - 1997-2003 :: 2002 - Slight Vibration In Rear End When Cruising Down The Highway
Jan 5, 2016
Noticed my 2002 F150 had a very slight vibration in the seat / steering wheel when cruising down the highway at 60 MPH.. Very slight, but was not there 2 weeks ago.. It seem to get a little worst as the 2 weeks progressed. Got all 4 tires balanced and rotated... no luck...Took both rear wheels off-- no problems with tires -- checked bearing clearance-- pushed and twisted on driveshaft yolk to check pinion bearing... nothing found......... last resort was drop back end of driveshaft and check U-joint.. It was tight and dry. Put drive shaft in 12 ton press and pushed out the u-joint bearings. Very dry and joint pins were starting to spall....... I mention this because I had checked " clearance" and "slop" and had "no noise" before removal... Truck has 139K miles on original u-joints .......... Something to keep in mind. Eventually it would have worn to the point that it was obvious, but in the first stages of failure, you just get small symptoms.

I just had an exhaust manifold replaced on my F-150. It has the small 8 cyl.. While the manifold was leaking, the truck of course ran like crap.....spitting, sputtering, barfing, etc.
Now that the manifold work has been done, the truck runs pretty well, except for some intermittent increase in throttle (not by me) when cruising at highway speeds. This is comparable to the "feathering" of the throttle that you would do when checking for engine noises.
Hard to explain without feeling dopey, but kind of a mild ruuum, ruuum, ruuum out of nowhere when I'm cruising along. I drive a 5 hr. trip every weekend, and it will do this about every 10-20 minutes.

I haven't really gotten under it to check this out, but my truck (see signature) has a slight vibration on take off. It only does it when the wheels are turned to the right or left. They don't have to be turned very far either. It doesn't do it on straight line take offs, or on a take off from a rolling stop. ONLY when pulling off from a dead stop and the front wheels are turned any degree to the right or left. I'm running mostly bald all terrain tires, the wheels are not bent. My current wheels are new to the truck, and the problem was there with the previous rim/tire combination. The rear end doesn't seem to have any slack in it. The transmission shifts like a top. There are no other clanks or vibrations anywhere in the drivetrain and it drives good.

Our FWD Santa Fe Limited had a very noticeable vibration that started around 60mph. Oddly, the vibration will sometimes come and go while cruising at a constant speed on the highway. We went about 30k miles before we had time to get it into the shop.
I asked them to rotate and balance the tires and the vibration was noticeably reduced...initially. Now it's back!
The car has ~65k miles. All 4 Kumho tires match and I believe are original from the factory. I have kept all tires inflated properly.
Our car has the optional 18" wheels. Is it common for these to bend? What else could be the cause here?

I have 2002 f150, fx4, ext cab, 110000miles 5.4 automatic truck, i just replaced my spark plugs, it still have a little miss, thought spark plugs will resolve but its the same, im wondering if i should change O2 sensors? clean EGR Valve? IAC valve? i am not getting good gas mileage and maybe its this missfire or something, its runs good without any problems, just this slight miss makes me think if its the cause to bad MPG.
I tried to find threads with pictures of how to change O2, how to clean EGR, and IAC, i remember seeing these threads but cant find em. And you think these three things will resolve my MPG and the slight miss?

2002 5.4L XLT. Just want to upgrade the exhaust on a budget to get better mpg. Pretty settled on a Flowmaster 40 swapped in, no fancy pipes or tips or anything. Just wanted to know how the interior drone was at highway speeds (75-80). I drive 15-20 min of highway to/from work give or take if I get off and take back roads home.

My friends truck is having a problem, and I haven't found any info on the specific issue. when you shift from P to D and accelerate, there's a slight grinding clatter in the tranny i think, bump it to 2 and the noise is completely gone! pull it to 1, and there she is again, also in reverse it does this, speed is not a factor, only the specific gears. i had read a thread which mentioned a "sun gear", and also that 1st and R are on the same bands?
I believe it was for a manual tranny that I had read about, but what this could be?! he's got a slight drag on the rear brakes, i assume it's his E-brake, could that have caused a transmission failure? We've removed the driveshaft and checked u-joints and all, nothing there, but when the truck reverses on the ground, you can watch the driveshaft bounce like it's binding. We grease the slip joint while we had it off, and we were able to spin the rear wheels by turning driveshaft w no problem while off the ground.

I've got a 02 Camry with a manual. In 5th gear, cruising on highway, there's a low grinding/ rattling noise. it doesn't do it if you try to accelerate, or if you have no throttle input at all, meaning it only makes the noise when trying to keep one speed, typically around 2000-2500 rpm. If i grab the shifter and apply pressure in any direction, the noise goes away. I've owned the car for 3 years now and its always done it, and hasn't gotten any worse or changed at all. I'm experiencing no performance issues and just chalked this up to gear noise, but recently read someone else was having same issue, and everyone was clamoring on about needing new bearings.

Bought the truck 1000 miles from home, ran great, checked oil it was black and well used, coolant was milky and degas bottle had some pressure in it.
Drove 200 miles fine, 75mph lots of power, no smoke, no overheating.
While cruising felt slight stumble, and lost hot air from the heater (started blowing cold), saw temp needle move slightly (still under 1/2 mark) and pulled over. Truck stalled on the offramp, and I was not able to get it to fire. I checked oil and it was same dark black. Coolant was low, down to about 2.5 gallons.
Towed it home, oil change, coolant flush, new thermostat, rebuilt IPR, and it fired right up. Ran great, smooth. Noticed slight haze out of the exhaust at idle, and puffs of white smoke when on throttle. Checked oil and it was milky. Where to look?

Picked up an R about a month ago. Have noticed a harmonic vibration when cruising just above 70 mph to 75 mph from the rear. I can assure you that it is not the wheel balance. Seems to go away if I depress the clutch. I'm thinking it is the butterfly valve on the muffler not fully closing and creating a resonance by fluttering at the rpms (exhaust flow) between 70-75 mph. I haven't tried disconnecting/plugging the vacuum line yet.

I have 2002 5.4L f150 120k miles. Bought it almost 2 years ago and did not notice this vibration at the time but it could have been there and I didn't realize it. The trans was replaced by ford with a reman at 90k. I'd assume they inspected the trans mounts but who knows.
At idle only, there is a vibration. Enough that I can see water in a bottle moving and a plastic bag shake., felt through the seat, hand on engine can feel it, can feel it through the door..etc. Very annoying. At 700-750 rpm it goes away. Happens in all gears. I don't want to shotgun approach this. What I've done: Replaced plugs and coils since it needed them anyway. They looked good! No difference. I've sprayed the maf down and cleaned the throttle plate (I know your not supposed to but some 16 year old will try to tell me it cured his idle and he gained 10 mpg, so I figured I would mention it). I've removed the IAC and cleaned it, plunger moves freely. My idle does not fluctuate. I have watched mode $6, it's not a misfire. I have removed the pcv hose and checked for cracks - it's in good shape. Replaced the pcv since it's cheap. Ran Chevron tehcron through it. Checked codes - nothing. I have an edge and it happens on all tunes as well as stock.
I have ability to read live data but do not know enough to interpret it, so that is about useless unless you can provide me acceptible ranges.

Last night I bought 2000 F250, 346k on it... Crew cab short bed 4x4 with ranch hand bumpers like I wanted .... Headed back home (Miami FL ~1100mi) and covered about 200 miles @70-75mph before i ran into few problems ....
First off, while cruising I noticed slight hesitation in the throttle, with loss of speed regardless of pedal pressure, noticeable on inclines. It would go away on downhill and get smooth response again and pick up speed. This went on for about 40 miles.
Then I noticed heater blower stop blowing hot and start blowing cold, without me changing any settings. At the same moment, I noticed temp gauge move up and I hit next exit offramp to check what's up. During right turn at the end of off ramp truck stalled. Pulled to the shoulder, and popped hood.
Noticed empty degass/overflow bottle. Carefully opened lid and water gushed up to the top. When all pressure slowly released, water pulled down and emptied the bottle. Both upper and lower radiator hoses are empty. Engine oil has no traces of water tho. There were no leaks under the truck. I then tried to fire up the truck to get me to the gas station 1/8th mile away.
No crank in Park. WTS comes on and goes off. Cranks in Neutral, RPMs come up some, oil pressure shoots up to normal running position, but won't fire. Tried a while then gave up as not to kill starter and batteries completely.
Fuel pump works 20 sec then shuts off. There is fuel in bowl. I covered 140 miles since last full fill up, so not fuel pickup issue I don't think.
Summary
Have crank
Have RPM
Have oil pressure
Have fuel
Have (had) batteries, now not so hot
It's cold out ....

I have a 1999 F-150, 4.2L V6 with 206,000 miles that recently developed a rear-end shudder/vibration. According to my door jam axle code (27) and the axle tag (3 37), I have what appears to be a conventional rear differential, even though most of my research would indicate this rear-end is for the F-250. In any case, and based on other online research, I changed the differential oil with a 75W-140 synthetic and added 4oz of a friction modifier. Now the vibration appears to be worse. It primarily vibrates when taking off from a stop, whether turning or not.
I have felt the vibration at speeds up to 60mph, but it is more noticeable at lower speeds. The vibration also seems to diminish after driving the truck for longer periods of time, particularly if at highway speeds. In other words, when I drive to and from work, which is about 30 minutes each way of mostly highway, the vibration is barely noticeable once I exit the highway and slow back down to 35-40mph. When feeling the vibration, if I decelerate, the vibration immediately ceases, but starts again when I accelerate. It's not as noticeable if I accelerate harder, but I generally don't do that. The gears inside the differential didn't have any noticeable wear, chips or slop/play. What may be plaguing my usual trouble-free F150?

Last August I bought a 2002 Ford F 150 extended cab 4x4 only until the weather got really cold did I start noticing this kind of like almost vibration or like the rear end is slipping but it doesn't happen all the time it only happens when I take off but once I get driving then it goes away...

I recently bought a 2003 F150 sport Scab 4x4 with 75k miles from a Ford dealer with a 4.6l auto. we didn't notice it when we test drove it but it has a squeak when going 0-10 mph in forward or reverse. The story goes a week after getting it home we started noticing a vibration and thudding in the rear end when braking so I take it back to the dealer (50 mile trip 1 way) and when I get there the drivers side rear rim is 30 degrees hotter than the passengers so the tear it apart and find the e-brake was dragging so they lube it up and tell me its good to go. I made it around the building and now I feel it dragging iddling around the parking lot and it is still squeaking so I take it right back in.
Long story short after going through this 2 times that day and bringing it back another day they replaced rear pads, calipers, roters and the hoses going to the caliper and tell me its good to go. Well it no longer had the dragging feel and I had to drive through DC traffic so I beat feet for home and on the way noticed its still sqeaking. I call them and they tell me to put a thousand miles on it and maybe the pads just need to wear in (??). so I took a road trip and 1.2k miles later it still squeaks.
I have tried to tell them it may be the u joints (after searching on here I learned that I am taking it back tomorrow and going to try and get something done but they are still saying its something to do with the brakes and probably won't do the u-joints. Normally, they are filling up the gas tank every trip up there and its all been under warranty (gonna see about getting the warrenty extended tomorrow due to this problem has been ongoing since we got it). Should I just let them run their own course and keep making trips back and forth?

I have just over 11K miles on my 2011 and now notice steering wheel vibration & slight shake at 70 mph. The passenger can also feel it.

This has been happening for the past 6 months or so. I recently had new ball joints, 4 wheel alignment, and 4 wheel balance. Even with this I'm noticing a very slight high frequency vibration at highway speeds. I noticed on one of the front wheels that a weight fell off, so this might explain the high speed vibration.
However - When I'm starting at 0mph, and accelerate to say 50mph for example, the car vibrates rather substantially as the speedometer moves from around 25mph to just past 30mph. After those speeds it goes away.
I've also noticed that it tends to be worse if I'm going up hill, which, according to the laws of physics, would tell me that going uphill would put more pressure on the front end, given it's heavier with the engine there. If I'm going downhill it vibrates much less.
When I drive I tend to not accelerate quickly, meaning, I don't 'punch' it, and accelerate gradually instead. If I'm driving on a level, well-paved road, and accelerate quicker than regular, the vibration seems to not be as heavy.
Any other tests for this? Struts, control arm, steering knuckle, drive shaft ?

What is the degree of difficulty in replacing the rear shocks on a 2WD 2002 F150?

I have a 2002 F150 4.6 liter 2 wheel drive with 49000 original miles, 30000 of that in the past 2 years. on a recent road trip the right rear disk brake caliper jammed in city traffic. I limped into a local repair shop with the right rear brake smoking. I rolled out with all new rear rotors pads and calipers. The mechanic could not locate new brake hoses. These hoses and lines are one piece from the caliper to the T fitting on the axle. Even the ford dealer could not locate the right rear brake lines.
Made it home 450 miles but the right rear caliper is still dragging a little on the new rotor. Seems to be about 40F hotter than the left side. I have spent the day trying to find replacements and can find the left side in one piece but not the right side. I have looked at the the union where the hose and line connect and there is no hex on the line side of the fitting its just round. You can see where the mechanic put a pipe wrench on the round and tried to break the two pieces apart but no luck.

I've recently purchased a 02 F-150 4x4 with 135k showing. About a week after purchase 4 COP's were replaced to eliminate a skip that started the day I drove it home. After a few hundred more miles it started shuttering at take off, much the same as the trans shuttering usually in higher gears/speeds. Only does it briefly in 1st gear and occasionally it goes into 2nd, but stops immediately after shift. After about 10 miles it stops doing it and until the trucks sits awhile it stays gone. About the same time a popping sound started coming from the rear axle at slow speeds. It changes sides as you drive and turn, and sometimes goes away intermittently altogether. Also is it possible or probable the two are related ?
